I l y BrieIy'stated-,an important objectief invention is to 'provide 'a shock.' absorber which' may be conveniently applied tef a motor vehicle of standard eoinstiaction.Withiout altering the construction of'ftheautimobile and Without in any Way interfering `with the Voperation or controlof the same;

A u-rtherobjiect 'of the' inventioni's to provide a v shock absorber having reliable.

means te check thel rebound of the vehicle,v

' which rebound renders riding" over rough rea-ds' more or vless unpleasant', especially when rrding in a light velnele.n Y

a autres @biete of the investies is sa ,provide av shock absorber of the character speeifreclr which is of' lfriglrly simplified cone struction, durable in use; andiis'r cheapto manufacture. f v Y vrOther objects ancl a'dvaanta'ges4 ap?

In the drawing, ;the numeral 5 designates the relatively movable portion of an automobile such as the front axle or the differentialV housing Vand the numeral 6` designates thel relatively fixed portion of an automobile such as the frame of the chassis.

The main leaves or plates 8 and 9 of the shock absorber are arranged in overlapping relation and are provided at their inner ends With transversely extending sleeves or rolled portions 10 for the reception' of anattaching pins 11 which as plainly illustrated -in Figure 1 extend 'through the side plates 12 of the friction member 14.V Eachfriction member 14 might be said to be in the form of a 'substantially U-shaped member, kthe bight portion of which' is provided with fric-V tion strip 'lrheldin place by fastening Vcle-- vices 16 andbeing similar in formation to ordinary brake lining.A Fig. 1 plainly illustion ofthe automobile.'

Qand 3 the single leaf 40 is secured at its upper endto a bracket 41 Which isin turn secured toarelatively fixed portion ,42 of the vehicle.

The'lowery portion ofthe leaf 40y is movable between friction elements 44 and 45, the

friction element45 being carried by a supporting bracket 46 rigidly secured toy the axle 47v or othermovable portion ofthe vehicle by means of Vclamps 48 and 49, the lsaid clamps being connected and held in place by means of fastenin devices 50.

Fig. '2 illustrates t fat the friction member 44 is'connected Vas 'indicated at 53 to the sides 54,'which are in turn pivoted as indicated at 56 to aU-shaped attaching member57.V f

Fig. 3 illustrates that a coil spring 58 is confined between a Vplate 59 andthe bight portion of the U-shaped member 57 and the spring 58 urges the friction element-44 into v'braking contact with the leaf 40'wher'eby the separation of thebodies ,42 and 47 isl` retarded. However this arrangement does not in any way interfere with the movement of the bodies 42 and 47 toward each other.

Withreference to the foregoing descrip# tion taken in connection 'with the accompanying drawing itA will be seen thatshock 1 absorber constructed in acordance with this Vherewith shownand described are to be `taken*merely as preferred examples of the same and such'V minor Ychanges and .arrange- Y `me`ntsrand construction of parts may be made as will remain within the spirit of the invention andthe scope of what is claimed. Having thus described the' invention, what is claimed is: y

l; A shock absorber comprising a bracket having attaching means and provided with an Y upstanding branch having a friction member, a pair of spacedparallel substantially L-shaped plates at opposite sidesl of said branch and pivotally connected thereto,

-a 'frictiongmember pivoted to said plates and `a leaf confined between said first yand second namedl friction members, and a v spring between said plates andurging said second named friction member into braking;

engagement with said leaf.

2.V A shock absorber comprising a bracket having attaching means and `a friction block, a pair 'vofspa'ced" plates. at opposite sides of -said block and pivotally connected thereto, a

friction block Vopposite said Yfirst-named block and connected to and positioned between said plates, a U-shaped'meinber having'sides pivoted to the lower terminal'p'ortions of said plates, and a spring positioned between and protected by the sides 'ofsaid U-shaped member and the lower portions of said plates and exerting a tension on said U-shaped meinberto urge the second-named v friction blockinto braking engagementgwith a leaf. 1

3. A shock absorber comprising a bracket havingfa friction block securely connected thereto, a pair of spaced parallelplates arranged atV opposite sides of said friction block and pivotally connected thereto, a-

friction .block pivotally connected to said spaced parallel'plates, a leaf positioned 'between said friction blocks, a U-sha'ped mein- Vber vpivoted to the lower portions of said spaced. parallel plates,ga coil springposif tioned between the sides of said U-shaped member and the lower portions of said Vspaced parallel'plates and protected thereby, said spring being adapted to exert a ten# sion on saidtl-shaped ineinberlto urge the second-named friction block into brakingV engagement with said leaf 4. Alshock absorber comprising a friction block, a pair ofplates pivoted toV opposite sides of said block, a friction block pivoted between said plates, aileaf positioned between said blocks, a U-shaped member pivoted to said-plates, a coil spring` positioned betweenand protected` by the sides of said Ushaped member and said plates,'and a pin extending centrally through said-spring.
